There is now an English-language demo of the Java applet, but it takes some work to get to. First, go to this URL: http://mathnet.math.technion.ac.il/ Then click on the text "English demo of MathNet". To log in use these credentials: Enter "demo" in the top input box. Enter "d" in the bottom input box. Press the button below (which is marked "הכנס"). Now, there will be a vertical menu on the left. Choose the second item, which is marked "שיעורי הכנה". The English-language tutorial is named "The Riemann Integral". Clicking this will open the Java tutorial. Note that the ability to tab between fields first appears in this tutorial on the seventh page, so you will need to be patient!
I do not think that they could have made this harder to get to! Dotan Cohen http://what-is-what.com http://gibberish.co.il
